Android source build...What next?

[khiremandar]

Hi,
I am java programmer but want to learn how Android OS works in different Hardwares.
I use 64bit Ubuntu 14.04.
I follow http://git.wandboard.org/git/?p=about for learn how to Build & Deploy Android-4.3.
After make command I thought as i got one image (same as by http://www.wandboard.org/images/downloads/android-4.4.2-wandboard-20140815.zip
this link i got img file & which i deployed it successfully on sd card in first attemt before using Source code, i run first Hello World App also) but i was wrong.
By make command in out folder there are 4 img files generated along with lots of files & folders named as
1. boot.img
2. ramdisk.img
3. ramdisk-recovery.img
4.recovery.img
5.system.img
Then i follow http://www.cnx-software.com/2013/07/25/wandboard-quad-unboxing-getting-started-with-android-and-linux-via-the-yocto-project/
Which shows instructions

chmod 6755 ~/wandboard/myandroid/out/target/product/wandboard/system/xbin/su
sudo umount /dev/sdX*
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/u-boot-6quad.bin of=/dev/sdX bs=1K seek=1 skip=1
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/boot.img of=/dev/sdX1
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/recover.img of=/dev/sdX2
sudo mount -t ext4 /dev/sdX5 /mnt
sudo cp -a ~/wandboard/myandroid/out/target/product/wandboard/system/* /mnt/
sudo unzip ~/wandboard/gapps-jb-20130301-signed.zip -d /tmp/
sudo cp -a /tmp/system/* /mnt/
sudo sync
sudo umount /dev/sdX

No errors but no success.
Can anybody give me hint/help etc which use for learning how to deploy Android 4.3 after completion of build?
How can i make one img file as i got from Download section?

Hello, khiremandar:

There is a "REAME" file under /wandboard-4.3-pre-source
Please follow the installation in README file.

Installation,
$ sudo dd if=/dev/zero of=/dev/sdX bs=1M count=1
$ sudo ./wand_fsl_sdcard-part.sh /dev/sdX
$ dd if=wand-4.3/bootable/bootloader/uboot-imx/SPL of=/dev/sdX bs=1K seek=1
$ sudo mount -t vfat /dev/sdX1 /media/imx6
$ sudo mount -t ext4 /dev/sdX5 /media/system
$ mkdir -p /media/imx6/boot
$ cp wand-4.3/kernel_imx/arch/arm/boot/uImage /media/imx6/boot/
$ cp wand-4.3/bootable/bootloader/uboot-imx/u-boot.img /media/imx6/boot/
$ cp wand-4.3/bootable/bootloader/uboot-imx/out.bmp.gz /media/imx6/boot/
$ cp wand-4.3/bootable/bootloader/uboot-imx/uEnv.txt /media/imx6/boot/
$ mkimage -A arm -O linux -T ramdisk -C none -a 0x10800800 -n "Android Root Filesystem" -d wand-4.3/out/target/product/wandboard/ramdisk.img /media/imx6/boot/uramdisk.img

(If you don't build android source with 'su' permission, please use "dd" command to install /system partition instead of "cp")
$ sudo cp -a wand-4.3/out/target/product/wandboard/system/* /media/system/
or
$ sudo dd if=wand-4.3/out/target/product/wandboard/system.img of=/dev/sdX5 && sudo sync

$ sudo umount /dev/sdX*

[khiremandar]

Thanks Richard,
Two points i notice after reading & using your reply as follows:-

1. by http://git.wandboard.org/git/ i follow steps for download source code

$ cd ~
$ mkdir -p wandboard/myandroid
$ cd wandboard/myandroid
$ curl http://commondatastorage.googleapis.com ... loads/repo > ./repo
$ chmod a+x ./repo
$ ./repo init -u https://android.googlesource.com/platform/manifest -b android-4.3_r2.1
$ curl http://git.wandboard.org/git/manifest.g ... _wandboard > .repo/manifest.xml
$ ./repo sync -j4
Build Android
$ cd ~/wandboard/myandroid
$ source build/envsetup.sh
$ lunch wandboard-userdebug
$ make

in downloaded source folders there is nothing like

There is a "REAME" file under /wandboard-4.3-pre-source

2. as given instructions

$ sudo ./wand_fsl_sdcard-part.sh /dev/sdb

i found fsl-sdcard-partition.sh in /device/fsl/common/tools
if i use this script i cant use next given command by you.

sudo mount -t vfat /dev/sdX1 /media/imx6

is some thing more missing by me?

[omid]

Hi khiremandar,
I suggest you to Download Android4.3 or 4.4 source code from wandboard.org download page and there is a README files follow the steps there and you won't have any problem

Download the source code : wget http://www.wandboard.org/images/downloa ... 625.tar.xz
And after compile
Do the following steps :


sudo dd if=/dev/zero of=/dev/sdX bs=1M count=1
sudo ./wand_fsl_sdcard-part.sh /dev/sdX
dd if=wand-4.3/bootable/bootloader/uboot-imx/SPL of=/dev/sdX bs=1K seek=1
sudo mount -t vfat /dev/sdX1 /media/imx6
sudo mount -t ext4 /dev/sdX5 /media/system
mkdir -p /media/imx6/boot ( first do this and then go to above command )
cp wand-4.3/kernel_imx/arch/arm/boot/uImage /media/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/u-boot.img /media/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/out.bmp.gz /media/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/uEnv.txt /media/imx6/boot/
mkimage -A arm -O linux -T ramdisk -C none -a 0x10800800 -n "Android Root Filesystem" -d wand-4.3/out/target/product/wandboard/ramdisk.img /media/imx6/boot/uramdisk.img
sudo cp -a wand-4.3/out/target/product/wandboard/system/* /media/system/ If you have problem after you put SD card into your board with booting then do the same thing but use dd command to copy system files into SD card
sudo umount /dev/sdX*

Best regards

[khiremandar]

Thanks omid,
i downloaded Android4.3 by http://www.wandboard.org/images/downloads/wandboard_android-4.3_fullsource_20140625.tar.xz
When i follow step

lunch wandboard-userdebug

i got message

No such file: wandboard-userdebug

What should i do? This message never appear when i build previously downloaded source.

[omid]

Hi , I am not expert in Android But i have not had this problem before ,
I suggest you to Download one more time or Download 4.4 version It is ok for me, After I downloaded I followed the steps wandboard-userdebug should be in source code ( make sure you are in the right directory wand4-3...) maybe you need to Download it one more time maybe some files did not download properly .
Another things that I can tell is make sure to download all these packages before compilation other wise you will get lots of errors

$ sudo apt-get install git gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
libgl1-mesa-dev g++-multilib mingw32 tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

make sure to install openJDK also

[khiremandar]

Thanks omid,
I done successfully as per readme file in Android 4.3.
I use following steps for installation(i change sdX to sdb as per my pc shows sd card as sdb)

sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
sudo ./wand_fsl_sdcard-part.sh /dev/sdb
dd if=wand-4.3/bootable/bootloader/uboot-imx/SPL of=/dev/sdb bs=1K seek=1
sudo mount -t vfat /dev/sdb1 /media/androiddev/imx6
sudo mount -t ext4 /dev/sdb5 /media/androiddev/system
mkdir -p /media/androiddev/imx6/boot
cp wand-4.3/kernel_imx/arch/arm/boot/uImage /media/androiddev/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/u-boot.img /media/androiddev/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/out.bmp.gz /media/androiddev/imx6/boot/
cp wand-4.3/bootable/bootloader/uboot-imx/uEnv.txt /media/androiddev/imx6/boot/
mkimage -A arm -O linux -T ramdisk -C none -a 0x10800800 -n "Android Root Filesystem" -d wand-4.3/out/target/product/wandboard/ramdisk.img /media/androiddev/imx6/boot/uramdisk.img
sudo cp -a wand-4.3/out/target/product/wandboard/system/* /media/androiddev/system/
sudo umount /dev/sdb*

No error in console. But when i put SD card in wandboard, it shows only wandboard image in screen. I attached HDMI screen.
Why not it boot i dont understand!
When i use only image file from http://www.wandboard.org/images/downloads/android-4.4.2-wandboard-20140815.zip
then after successful running Android i check SD card by gparted & it shows partitioning as follows


but when i make & install android 4.3 source code which i got from tar file, i cant even boot?
Is anything i forgot to do? Is readme installation instructions are complete?

[khiremandar]

After using installation steps given in readme, i can see sd card in gparted as follows:-


when i see sd card in disk utility
i can see it as follows:-










i will upload successful Android 4.4 sd card's images which i can see in disk utility if required.

[khiremandar]

I try to run wandboard after freshly build & installation process as per given in Readme file inside the source tar file.
few things i observe when i follow installation steps:-
1. after first step which is

Code: Select all

sudo dd if=/dev/zero of=/dev/sdx bs=1M count=1

, if i not remove SD card reader from comuter & reattach it, i cant use step 4th
which is

Code: Select all

sudo mount -t vfat /dev/sdx1 /media/imx6

I didnt understand.
2. when i want to use

Code: Select all

sudo cp -a wand-4.3/out/target/product/wandboard/system/* /media/system/

i found this 'system' partition is read only.
When i check out folder which generated by make command it also read only, so i think it make read only partition.
So i change its permissions as 777 by chmod command, then freshly follow installation steps from start again after making sd card blank unallocated.
3. when i complete installation process, i attach serial communicator with pc & wandboard so i can get output in console.
in console i got as follows:-

Code: Select all

ram_console: uncorrectable error in header
ram_console: no valid data in buffer (sig = 0xf7ffffef)

is this thing giving trouble?
here i post whole console output which i get when i can see only wandboard logo for 1 sec & then nothing.

Code: Select all

I need help, where exactly going wrong in process of building & installation of Android OS.

[omid]

I don't know why you have this much problem with this
Did you compile successfully ? If yes do the followings I hope it works for you
1) put the SD card into your computer then sudo gparted then go to Device then

create partition table and after that go to partition->new it should delete all information on your SD card
Then . sudo blkid to find out what is the name of SD card it usually is sdb
then

sudo dd if=/dev/zero of=/dev/sdX bs=1M count=1

sudo ./wand_fsl_sdcard-part.sh /dev/sdX ( it should takes around one minutes and make new patitions for your SD card )

dd if=wand-4.3/bootable/bootloader/uboot-imx/SPL of=/dev/sdX bs=1K seek=1

mkdir /media/imx6/boot

sudo mount -t vfat /dev/sdX1 /media/imx6
sudo mount -t ext4 /dev/sdX5 /media/system

sudo cp wand-4.3/kernel_imx/arch/arm/boot/uImage /media/imx6/boot/
sudo cp wand-4.3/bootable/bootloader/uboot-imx/u-boot.img /media/imx6/boot/
sudo wand-4.3/bootable/bootloader/uboot-imx/out.bmp.gz /media/imx6/boot/
sudo wand-4.3/bootable/bootloader/uboot-imx/uEnv.txt /media/imx6/boot/ ( go to wand4-3/settings ) and copy the boot arguments that you want to use )
sudo mkimage -A arm -O linux -T ramdisk -C none -a 0x10800800 -n "Android Root Filesystem" -d wand-4.3/out/target/product/wandboard/ramdisk.img /media/imx6/boot/uramdisk.img


sudo cp -a wand-4.3/out/target/product/wandboard/system/* /media/system/ ( or use dd command to copy this files if it doesnt work )

It should work
Best regards
